RECEIVING AND LOADING HOPPER.

Application filed March 6, 1925. Serial No. 13,523.

To all whom it may concern.

Be it known that I, HAROLD G. MEAD, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a new and useful Improvement in Receiving and Loading Hoppers,of which the following is a specification.

This invention relates to improvements in hoppers, and more especiallyto a hopper adapted for use in connection with continuous loading aspracticed, for example, in mining.

In my oo-pending application (Serial Number 13,522 of even dateherewith) covering inventions in the art of mining, I have shown anddescribed a method of mining making use, in general, of a loadingmachine placed in a room at the face of the material adapted to pick upthe shot material and deliver the same in a continuous stream into aproper receptacle. The re ceptacle there shown comprises what I havetermed a receiving and loading hopper. From this hopper, a shuttle cartakes loads intermittently and carries them to the stub entry or roomentry where the shuttle car is unloaded by a shuttle car unloader andthe contents dumped into the mine cars operating in the cross entry. Thehopper described and claimed in this application way be termeda,receiving and loading hopper and is so designed that it is especiallyadapted for use in the method of mining described in said co-pendingapplication. It is obvious, however, that it may be used in other waysand for other purposes, without detracting from the spirit of thisinvention.

In that form of device embodying the features of my invention shown inthe accompanying drawings, Figure 1 is a vertical sectional view of theimproved hopper, Fig. 2 is a view taken as indicated by the line 2 ofFig. 1, and Fig. 3 is a view taken as indicated by the line 3 of Fig. 1.

As shown in the drawings, 10 indicates the hopper which is supported inany suitable manner as for example by the legs 11, 11. The hopper isheld a suflicient distance above the floor in order to permit a car 12to go under the same. The car 12 here shown may, for example, be theshuttle car spoken of in my co-pending application above referred tocovering a continuous loading method of mining.

The shuttle car 12 is adapted to go under the hopper 10 from the righthand side (as viewed in Fig. 1) moving to the left until it is exactlyunder the hopper as shown in Fig. 1. In leaving the hopper the car movesto the right (as viewed in Fig. 1). The end of the hopper at which theshuttle car enters and leaves, that is the right hand end (as viewed inFig. 1) I will designate as the front of the hopper.

The rear half of the bottom of the hopper is formed by a stationaryplate or bottom section ll; and the front half comprises two slidingplates or bottom sections 15, 15, one operating on each side of acentrally arranged longitudinal bottom supporting strip 13 and adaptedto slide between the channel members 16, 16. Since the construction andoperation of each of the sliding sections 15 is the same, I willdescribe in detail but one.

The sliding section 15 is adapted to slide under the stationary section14:. Near the front edge of the section 15 on the under side there isprovided a downwardly projecting lug 17. In front of the lug 17' is apair of shorter lugs 18, 18. Arranged betweenthe lugs 18 is a verticallymovable latch member comprising an inverted U- shaped piece 19projecting through a hole 19 in the plate 15 and carrying at its lowerend a beveled latch 20. At the front of the hopper on the under side ismounted a wedge-shaped member 21 adapted to go through the U-shapedpiece 19 and raise the same upon'forward movement of the bottom section15.

The operation of the device is as follows. When the shuttle car 12 isnot under the hopper, the bottom of the hopper is closed. That is, thetwo sliding sections 15 are both to the right as far as they will go,thus forming a complete closure for the bottom with the stationarysection 14. As the shuttle car 12 starts to go under the hopper, theupper edge of its front side 22 engages the lugs 17 on the slidingsections 15. Further movement of the shuttle car 12 slides thesesections to the left, thus permitting material to flow from the hopperinto the shuttle car 12. As the sections 15 move to the left, themembers 19 ride down off of the wedges 21 thus permitting the latches 20to drop into place, as shown in Fig. 1, on the right hand side of theupper edge of the front face 22 of the car. As the car 12 moves to theright to leave the hopper, the upper edge of the -face 2 engages withthe latches 20 to draw the sections 15 into closed position. is theyreach the entirely closed position, the U-shaped members 19 ride up onthe wedges 21 thus lifting the latch members to permit, the car to leavethe hopper. It will be seen, therefore, that the shuttle car 1'12 inthus going under the hopper opens the bottom to receive a load ofmaterial and in leaving the hopper again, closes the bottom to preventmaterial from falling out on the floor.

\Vhile I have shown and described certain embodiments of my invention,it is to be understood that it is capable of many modifications.Changes, therefore, in the construction and arrangement may be madewithout departing from the spirit and scope of the invention asdisclosed in the appended claims, in which it is my intention to claimall novelty inherent in my invention broadly as possible in view oi theprior art.

It is to be noted that the hopper is supported on the legs 11; and thatthese legs may be removed or folded up out of the way. The appa atus isso constructed that the hopper can be carried from placeto place on thecar. This is easily accomplished by removing or "folding the legs 11 outof the way thus allowing the hopper to rest on the car and be carriedthereby.

What I claim as new, and desire to secure by Letters Patent, is:

1. A hopper adapted to receive a continuous supply of material; a caradapted to receive a load of material from the hopper; means forsupporting the hopper a sufficient distance above the floor to permitthe ear to go under the same; means operated by movement of the car to aposition under the hopper to open the hopper and discharge a load ofmaterial into the car; means operated by movement of the car in leavinga position under the hopper to close said hopper and prevent furtherdischarge of material therefrom; and means whereby the hopper can becarried on the car.

2.
